Abstract: A methodology for representing hierarchical relationships between data in cells utilizes formatting of rows, columns, and cell borders, as well as blank rows. Such formatting and data table structure can be manipulated manually by a user, or automatically by software code, or via some combination of the two. The methodology involves first setting hierarchical relationships between columns or group of columns, or rows and groups of rows, in a spreadsheet or other document as levels and/or groups. Preferably, hierarchical relationships between data added to cells defined in different levels is represented by formatting a connecting border between cells in different levels with a line on either a left or right side (e.g. for columns) or a top or bottom (e.g. for rows).

Abstract: A combustor for a gas turbine engine that facilitates reducing combustor chamber dump pressure losses to improve combustor and engine performance is described. The combustor includes a diffuser that diffuses airflow directed into the combustor. The diffuser includes an outer wall, an inner wall, and a plurality of splitter vanes between the outer wall and the inner wall. The splitter vanes are spaced radially apart, and each is spaced radially from a respective diffuser wall such that an outer passage, an inner passage, and a central passage are defined by the splitter vanes.
